If we have a Class C amplifier feeding power to the same antenna and

50% of the available energy. So, the transmitting antenna system can be
more efficient than the receiving antenna system, it seems to me.

Comparing a Class C amplifier to a linear receive antenna source is comparing
apples and oranges. If one makes the transmitter Class-A linear (like the
receive antenna is linear) then the antenna is reciprocal for transmit and
receive. (A Class C or Class B or even Class AB *single stage* is not linear).
Putting two of them in push-pull doesn't make the individual single stages linear.
